Environmental Protection And Environmental Engineering Project In Highway Construction At Environmental Sensitive Area

In China,Highway,which can improve transportation network,is rapidly constructed and has became an important channel connecting each area.First of all,This paper gives a theoretical research on environmental protection in the construction of highways both in domestic and overseas.Then,the paper explores environmental issues arising from the environmrntal crisis in QinLing Mountains,ShaanXi Province,and according to local conditions,designs a environmental engineering project to protect local environment and restore the natural ecological environment as much as possible.The detail of the project as follows:When highway is constructed in the environmental sensitive areas of mountains,the protection of the sound environment is mainly set based on environmental sensitivity.Normally,There are residential areas,school,ect,along the moutain area.It's usually distributed on both side of road.Through the measurement and calculation,this paper designs six noise barrier protection systems used in sound environmental sensitivity,and after comparing all noise reducing measures,the project finally chooses composite metal sound-absorbing board as a mainly measure to broadening the audio band absorption and improve the effect of noise reduction.Then,the prevention of water resource is essential in the construction of highway in the mountains.Especially for the project mentioned in this paper,which through the area of protection of water source.Two waterways of them are sensitive to water,one is CheDao River,which is through many times or parallel,the other is ShaShen River,which is crossed by a bridge once.To solve this problem,the project set up a warning sign,and a bridge run off collecting pool for bridge a cross-river bridges to prevent runoff from flowing directly into sensitive fluids,and monitor the pool.Meanwhile,the design of spoil ground is very important for environmental sensitive areas in the process of soil and water conservation.This project has fully learned from the experience in the local soil and water conservation,and combined with actualities,a series of works such as,land reclamation has been done to improve the design of spoil ground.There are also some measures to prevent the water resource for temporary works,including construction camps,construction sites,make shift road for construction,etc.Given the construction and subsequent operations that may lead to the dangers of water runoff,this paper has designed a feasible project to prevent the water conservation.
